Slow NDMP Backups with OnTap 7.2.4L1. (79818)

Date: Jan 2010
Product & Version: NetVault 8.5
OS Version: All
Module & Version: NDMP 7.1.11
Application version:


Symptoms:
Backing up data from a NetApp Filer (OnTap 7.2.4L1) to a Quantum tape library that is attached via SCSI to the NetVault Server.
Upgrading the NetVault Server and NDMP Plugin to the latest versions had made no difference.
After setting up Drive Statistics on all of the backup drives and analyzing the results, the conclusion was a slow data source.

Upgrading the NetApp Filer OnTap version from 7.2.4L1 to 7.3.2 and rebooting it cured the issue.
The Data Transfer Rate had risen from 11 MB/s up to 75MB/s.
